Data
cards may be programmed directly in the GPSMAP 276C using the USB
interface. For remote programming, cards may be loaded using the USB
Data Card Programmer
Only
maps from MapSource CDROMs can be downloaded into the GPSMAP 276C. Mapping products such
as Fugawi and Ozi
Explorer can be used in conjunction with digital maps (e.g. your
own scanned maps, or maps on CDROM from Fugawi and Spectrum Digital Imaging ) to perform advanced handling of user data, but these maps CANNOT
be downloaded into the Garmin GPS receivers or data cards.
